For this section, no need to solve the questions and submit answers Your company is a major distributor of coffee in the UAE. You can buy coffee from 5 roasters and distribute the coffee to three UAE cities (Al-Ain Abu Dhabi and Dubai). The monthly demand in the three cities is as follows: City Monthly Demand (tons) 1. Al-Ain 50 2- Abu Dhabi 120 3. Dubai 280 order to guarantee supplies from the five coffee roasters, you need to sign a monthly contract with fee. If you decide to sign a contract with a roaster, you need to pay the contract fee and then you need to pay for transportation cost of any coffee supplied from the roaster to the 3 cities. The production capacity of each roaster and their monthly fee are as follows: Roaster Monthly Supply (tons) Monthly Fee (contract) 75 5800 B 150 $1200 175 $1350 D 200 $1500 E 125 $1000 The transportation cost per ton of coffee from roasters to the 3 UAE cities is as follows: Roaster Al-Ain Abu Dhabi Dubai $5 SB 56 53 $6 57 $4 $9 96 D $8 SS $9 E 57 59 $2 Your company asked you to minimze the total monthly cost of coffee supply from the five roasters and distribution to the three UAE cities B Your company asked you to minimize the total monthly cost of coffee supply from the five roasters and distribution to the three UAE cities. 12.
